What is the role of DHA in early development?

• A. DHA is primarily linked to bone density.
• B. DHA supports eye health only.
• C. DHA supports neuronal membrane fluidity and cognitive development.
• D. DHA has no role in development.

Answer: (C)

DHA is a long-chain omega-3 fatty acid that becomes a major structural component of brain and retinal cell membranes during fetal life and early infancy. This placement helps keep membranes fluid, which supports receptor function, neurotransmitter signaling, and the growth of neurons and synapses as the brain develops rapidly. Because early development relies on the integrity of neuronal membranes and the formation of neural connections, adequate DHA intake is linked to better cognitive development and visual maturation. So, DHA’s main role in early development is to support neuronal membrane fluidity and cognitive development. It’s not primarily about bone density, and while it contributes to eye health, its broader impact on brain development is the key concept.
